11305 is the volume of the red cylinder
45 cars=454
Divide 45 on both sides to get the average length of a single car
1 car = 10.01 ft
<h2>
Answer:</h2>
<em><u>Distance of the farmer's rectangular field around the field = 74.46 m</u></em>
<h2>
Step-by-step explanation:</h2>
In the given question,
Length of the rectangular field, L = 20.33 m
Width of the rectangular field, W = 16.9 m
Now,
The area of rectangular field is given by,
The total distance around the rectangular field is,
Distance = Perimeter of the the rectangle.
Perimeter of rectangle = 2(Length + Width)
Perimeter = 2(20.33 + 16.9)
Perimeter = 2(37.23)
Perimeter = 74.46 m
So,
<em><u>Distance of the farmer's rectangular field around the field is = 74.46 m</u></em>
